hi sarah,
i have been away from your forum for a while(i'm a lurker, though; this is my first post), and i have been using your 1.5 dermaroller since september 2010 for facial acne scars. i have some questions re: single needling and dermarolling. i'm sorry if this question has been asked before, but i couldn't find it anywhere in the forum. as well, i need some clarification about rolling frequency.
1. i have lots of scars. when i needle each one of them once per month(i don't like single needling many at once because i get too many red spots on my face. so, i only do a few at a time), some end up getting needled very close to the time i have to use the 1.5 dermaroller. how does dermarolling affect the collagen synthesis that's already happening in those scars that were needled late in time? does dermarolling conflict with needling in any way?
2. your dermarolling instructions re: 1.5 rollers and their frequency of use have changed since i bought mine in august 2010. if i'm not mistaken, the instructions now say one can use the 1.5 every 3-4 weeks; before it was every 4 weeks at most. what changed this? why did your recommendation change? do you still recommend spacing it's use 5-6 weeks apart?
thank you very much!
